Fortress Peak – 13,241

RT Length: 5.76 miles

Elevation: 2482’

I know most people hike Fortress and Precipice Peaks together, but for personal reasons, I wanted to hike them over the course of a couple days. I parked at the Wetterhorn Basin Trailhead, and was greeted to a herd of cows. They were all over the basin, and would be my companions for the next few days. They had a penchant for licking my truck. The drive in is 2WD on a dirt road until 2 miles before the trailhead, where it becomes 4WD and requires clearance. None of these pictures are as clear as I’d like. The fires weren’t helping in the morning, and the sun wasn’t helping with shadows in the early afternoon. I know not to head east early in the morning, but I did it anyway. Sorry!

I was on the trail at 6am, following Wetterhorn Basin Trail No 226 south for just under 1.5 miles.

After hiking for 1.4 miles, and at around 11050’, I came to a drainage, and followed it east

I came to an obvious “y” in the drainage, and went left, still following a drainage.

The drainage became narrower, so now I hiked to the left, trying to stay on tundra, but mostly staying on rocks

This next part is difficult to explain. You’re going to WANT to head straight up to the rock formation in front of you, but don’t do that. Instead, continue following the drainage, but aim to the right of the rock formation.

You’re trying to avoid the mess to the right of this picture… loose kitty litter on solid rock

Now is the time to put on your helmet. Ahead there’s a more solid gully to climb. You can climb either to the left or right, I chose right.

At the top of this gully is another gully to the northeast. This one was more difficult than the last. Solid on the sides with large scree down the center. I went straight up the center

And then walked on tundra to the ridge.

Once on the ridge, I turned right and followed it east, staying below the ridge. I noticed a cairn that marked an ok game trail, and followed that trail as it skirted below the ridge. The cairns especially helped in this area.

At 12700’, just before the rock formations directly in front of the trail, I left the trail and headed northeast for the ridge once again, this time on scree.

Back on the ridge, I followed it east towards the summit. The terrain here became slippery. Rocks the size of softballs and footballs were held together by dirt, and that’s what I was walking on. There were steep runnels on either side of the trail, which at times was less than 2 feet wide. A slip would have been dangerous here, on either side. This was all class 2, but I’d advise wearing microspikes for traction.

I summited Fortress Peak at 8:15am. There was a summit register in one of those pipe tubes, but the paper inside was so wet I didn’t want to disturb it, so I left it alone.

Here’s what some of that exposure looks like

Now to head back down. This was an out and back hike for me, so I just retraced my steps, back down the sketchy section with no traction just below the summit.

Then I hiked down the ridge until I was parallel with the rock formations on my left (circled). Here I turned and headed southwest towards the game trail.

I then followed the game trail back to the gullies. I descended near this big rock (circled).

Now for the second gully.

At the base of the second gully, I headed west towards the tundra ridge that would bring me to the drainage.

And now to follow the drainage back to Wetterhorn Basin Trail No 226

Back on Wetterhorn Basin Trail No 226, I followed it 1.4 miles north back to the trailhead.

Where the cows were still licking my truck

I made back down to the trailhead at 10:30am, making this a 5.76 mile hike with 2482’ of elevation gain in 4.5 hours.
